Niemann, Geschichte der Grafen von Mansfeld (Aschersleben, 1834).
ASCHERSLEBEN, a town of Germany, in the Prussian province of Saxony, 36 m.
Aschersleben was probably founded in the 11th century by Count Esico of Ballenstedt, the ancestor of the house of Anhalt, whose grandson, Otto, called himself count of Ascania and Aschersleben, deriving the former part of the title from his castle in the neighbourhood of the town.
(1315) Aschersleben passed into the hands of the bishop of Halberstadt, and at the peace of 16 4 8 was, with the bishopric, united to Brandenburg.
He died childless in 1319, and was succeeded by his nephew Henry II., who died in 1320, when the Ascanian family, as the descendants of Albert the Bear were called, from the Latinized form of the name of their ancestral castle of Aschersleben, became extinct.
On Henry's death in 1252 his three sons partitioned the principality and founded respectively the lines of Aschersleben, Bernburg and Zerbst.
The family ruling in Aschersleben became extinct in 1315, and this district was subsequently incorporated with the neighbouring bishopric of Halberstadt.
The brown coal region extends from Oschersleben by Kalbe to Weissenfels; it is also found in the neighbourhood of Aschersleben, Bitterfeld and Wittenberg.
The principal towns are Magdeburg, Halle, Erfurt, Halberstadt, Nordhausen, Miihlhausen, Aschersleben, Weissenfels and Zeitz.
